Guys, anyone give me a quick overview of the rules for swingouts. In middle of 6 pt roll bar build, and don't have rulebook. Yeah, I know...

Anyways, trying to figure out what I can do for swingouts. What is legal.

Thanks,
JesseJay

 

Rocker bar must be installed below and outside of drivers legs and must tie into the main hoop,the forward hoop,frame frame extention,or side diagonal.Rocker bar may not tie into swing-out side bar support.if rocker bar ties into side diagonal more than 5 inches (edge to edge) from forward roll -cage support or main hoop,a 1 5/8-inch x .083 CM or .118 ms brace/gusset is mandatory between the diagonal and forward roll-cage support or main hoop.

 

He's doing a 6 point "no forward hoop".

 

swing outs are legal to 8.50 as long as the shoulder bar passes between the top of the shoulder and the elbow.
this is a great set, I have used plenty on cars in the past

thanks for the link. I've seen those before. Pricey but cool. The issue I have ran into is that the location where I would put the rear part of the swingout is too far forward to be legal for NHRA. The stub connected to the main hoop will end up 12" out, and only up to 8" is legal. This is to clear my seat. So, I'm concerned my cage won't pass tech if I were to install swingouts.

 

Is the main hoop on the rear shelf or the floor?

 

It's on the floor.

 

you have me stumped. I am I guess looking at the same issues for my c6. I plan to install the bar in the same area and want to use a swing out also.

 

Maybe you can use the sliding sleeve design. Might make up fpr some length you need? Here is the what the book says:
Swing-out side bar permitted on OEM full-bodied car 8.50 e.t. and
slower. The following requirements (a through d) apply:
a. 1 5/8-inch O.D. x .083-inch CM or .118-inch MS minimum.
Bolts/pins must be 3/8-inch-diameter steel, minimum and in
double shear at both ends.
b. Male or female clevis(es) permitted. Male clevis must use two
minimum 1/8-inch-thick brackets (CM or MS) welded to each rollcage
upright; female must use minimum 1/4-inch-thick bracket
(CM or MS) welded to each roll-cage upright. Pins must be within
8 inches of the vertical portion of both the forward and main
hoops. A half-cup backing device must be welded to the vertical
portion of the main hoop (inward side) or the upper end of the
swing-out bar (outward side), minimum .118-inch wall (CM or
MS) extending at least 1 5/8 inches past the center of the pins. A
clevis assembly using a minimum .350-inch-thick male
component and two minimum .175-inch-thick female components
may use a 1/2-inch-diameter Grade 5 bolt and does not require a
half-cup backing device.
c. Sliding sleeves of 1 3/8-inch x .083 CM or .118 MS, with
minimum 2-inch engagement, are permitted in lieu of the upper
pin/cup.
d. All bolt/pin holes in the swing-out bar must have at least one-hole
diameter of material around the outside of the hole.

 

Raise the foward bar under the dash and then put the turn in it and you can set the swing out further back.You just have to reach over your shoulder with the opsite arm to pull the swing out pin.
